VALVE.

To all whom t may concern:

Be it known that l, JOHN F. BLooM, a citizen of the United States, residing at town oi St. Joseph, in? the county or St. Croix and State of Wisconsin, have invented certain new and useful Improvements in Valves, oi: which the following is a specification.

This invention relates to oscillating valves operated by hand and adapted to distribute tluid under pressure, such as steam, water r air, from an inlet to an outlet, and from the said outlet to an exhaust; and it com siste in the novel construction and combinan tion oit the parts hereinafter fully described andy claimed.

Tn the drawings, Figure 1 is a Jiront view of twosimilar threeway valves constructed according to `this invention and combined together so as to operate in conjunction. Fig.

2 is a longitudinal section through the right hand 'three-way valve shown in Fig. 1, showing the inlet closed and the outlet connected with the exhaust. Figs. 3 and l are crosssections through the right hand three-way valve, `taken on the line *JJ-zt' in Figs. 1 and 2. Fig. 3 shows the inlet connected with the outlet, and Fig. /l sh ws the outlet connected with thev exhaust. Fig. 5 is a cross-section similar to Fig. 3, but is taken through the lett hand three-'way valve on the line g/--3/ in Fig.`1, and shows the outlet connected with the exhaust, which is the setting which corresponds with that of the right hand valve as shown1 in Fig. e. Fig. 6 is a crossu section, taken on the line .ee-e in Fig. 1, and showsthe valve operating mechanism.

This valve may be used to distribute pressure liuid'to a press of any approved construction, or it may be used in connection with a system ot lire-extinguishing apparatus, and also for many other purposes. When used in conjunction, as shown in Fig.

1. the two similar' three-way valves are are` ranged right and left. As .both ot these valves are alike the following description will be confined to one oi them.

The body portion ot the valve is Ylorined of two separate casings 2 and 3, which are securednpon a base lcommon to both of them, or which are otherwise held relatively stationary. These two casings have a tuba-n `Specification `'of Letters Patent.

lar sleeve 5 secured inside them and extending between them. A valve 6 is arranged to oscillate -inside the sleeve, and is tapered slightly, and is tted by grinding it, so that there may be no leak between it and the sleeve. The valve 6 is hollow, and is provided with two chambers 7 and 8, arranged end to end and separated by ya partition 9.

The valve is operated or oscillated by means of a stud or shaft 10 which is secured to its smaller end. A handle 12 may be secured directly to this stud, but it is preferably pivoted in a bracket 14- secured to the base 4. This handle is provided with a toothed segment 15 whichgears into `a The Smal-ier eea persen er the valve ena the adjacent end ofthe sleeve are kept tight by means of a gland 17, which is secured to the casing 2, and a suitable cuppacking 18.

The adjacent ends of the two casings 2 and' 8 are kept tight with the sleeve by means of two similar glands 19 and packings 20. The other end portion of the sleeve has a circumferential rib 21 formed on it, and this rib engages with `an internal rib 22- ;tormed' on the casing 3. This end portion of the sleeve has a cylindrical vchamber' 24 formed in it, and 25' is a coverwhich is secured to the casing 3 by "bolts26L` This cover has a tubular extension 27 which itsinside the chamber 211 and forms an annular `passage 28 around the end portion of the sleeve. Packing material 29 is arranged between the endof the extension 27and the two ribs 21 and 22; and packing A pointed adjusting screw 31 engages with the cover 25 and bears against the end of the valve 6 at its axis, and operates to adjust the contact between the valve and the sleeve. The sleeve 5 is not fitted tightly in the two eaeings, but is kept tight in them by packing materialas hereinbefore de.-

scribed. This construction permits the valve and its sleeve to be takenout and replaced as often asthe wear between thein makes it desirable, and as this valve is used for distributing iiuid under high pressure it is essential that the valve and its sleeve should be kept in very good working condition.

rlChe inlet 32 oi"- the casing 2 communicates with a suitable inlet pipe 33 secured to the casingQ by any approved means. VIhe casing 2 has an annular passage 3a which com? niunicates constantly with the inlet 32 and also with two inlet ports torined in the sleeve 5, and arranged at opposite sides ot it to balance the pressure. rEhe chamber il of the valve is provided with two inlet ports 36 for communicating with the ports 35.

The other casing 3 has a relatively long annular passage 36 formed in it and arranged around the sleeve 5. This passage 36 communicates constantly with two similar outlet ports 3? formed in the sleeve and arranged at opposite .sides of it, and also with an outlet port 38 formed in the casing. The outlet port 33 of the casing is connected. with any suitable outlet pipe 39 secured to the casing. The chamber 7 ot the valve is provided with two outlet ports l0 for eonr lnunicating with the outlet ports 3'( in the sleeve.V

rl`he chamber 8 of the valve is provided with a pair of ports 42 arranged at opposite sides o it, and adapted to communicate with a pair of ports 43 formed in the sleeve which communicate constantly with the annular passage 36 in the casing 3. Thesevports 43 are shown in dotted lines in Fig. i), and they are preferably much wider than the ports l2 in the valve so that two similar valves can be arranged right and left as shown in Fig. l, without any change or alteration to their ports.

The chamber S of the valve is also provided with a pair of exhaust ports arranged ,at opposite sides of it and adapted to communicate with a pair o'l' wide ports 46 formed in the sleeve, and which are made wide for the saine reason the ports e3.

The ports 46 communicate constantly with the annular passage 2S oi' the tubular extension 27 o1c the cover 25 hereinbefore described. This tubu extension 27 has an exhaust port 4:7 which connects the annular passage 28 with an exhaust port 43 in the casing 3, andthis exhaust port 4:8 communicates with any suitable exhaust pipe i9 secured to the said casing.

When the valve is moved to theposition shown in Fig. 3, the pressure fluid passes from the inlet pipe 33 to the outlet pipe 39; and when the valve is inoved to the position shown in Figs. 2 and si, the pressure ffluid passes from the outlet pipe 39 to the exhaust pipe 4.9.

yThe left hand three-way valve shown in Fig.v 1 is set in a position relative to the right hand valve, so that the left hand valve is exhau l' fr the fluid from its outlet pipe when the i t hand valve is admitting pressure own. outlet pipe. These combined valves have their ninlet pipes formed as a i'orled pipe having a sing e inlet branch 50.
